They can give you
They are designed to be simple, durable, versatile,
as well as long lasting.
The batteries we use have a three year shelf life.
The unit is only 4½" long, 2½" wide, and 1¼" deep, pocket-sized!
My unit uses the Electro-colloidal* manufacturing method to create Colloidal Silver.
Each kit will make about 100 gallons of Colloidal Silver...
If you make 8 oz. of Colloidal Silver a week, the silver wire should last for about three years.
If you make less, it could last even longer.
* The electro-colloidal manufacturing process is generally considered to be the superior method of making colloidal silver
